A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Inter-Domain Routing WG of the IETF. Title : Revised Validation Procedure for BGP Flow Specifications Authors : James Uttaro Juan Alcaide Clarence Filsfils David Smith Pradosh Mohapatra Filename : draft-ietf-idr-bgp-flowspec-oid-08.txt Pages : 9 Date : 2019-05-09 Abstract: This document describes a modification to the validation procedure defined in RFC 5575bis for the dissemination of BGP flow specifications. RFC 5575bis requires that the originator of the flow specification matches the originator of the best-match unicast route for the destination prefix embedded in the flow specification. This allows only BGP speakers within the data forwarding path (such as autonomous system border routers) to originate BGP flow specifications. Though it is possible to disseminate such flow specifications directly from border routers, it may be operationally cumbersome in an autonomous system with a large number of border routers having complex BGP policies. The modification proposed herein enables flow specifications to be originated from a centralized BGP route controller.
